Abstract: A set of techniques is described for monitoring and analyzing crashes and other malfunctions in a multi-tenant computing environment (e.g. cloud computing environment). The computing environment may host many applications that are executed on different computing resource combinations. The combinations may include varying types and versions of hardware or software resources. A monitoring service is deployed to gather statistical data about the failures occurring in the computing environment. The statistical data is then analyzed to identify abnormally high failure patterns. The failure patterns may be associated with particular computing resource combinations being used to execute particular types of applications. Based on these failure patterns, suggestions can be issued to a user to execute the application using a different computing resource combination. Alternatively, the failure patterns may be used to modify or update the various resources in order to correct the potential malfunctions caused by the resource.

Abstract: A method of operating an automatic transfer switch to switch an electrical load from one power source to another power source includes measuring one or more characteristics of a switching circuit in the automatic transfer switch. A value of one or more timing variables is determined based on the measured characteristics of the switching circuit. The switching circuit is operated to close relays in the automatic transfer switch. The timing of closing of the relays is based on the value of the timing variables.

Abstract: In an environment such as a cloud computing environment where various guests can be provisioned on a host machine or other hardware device, it can be desirable to prevent those users from rebooting or otherwise restarting the machine or other resources using unauthorized information or images that can be obtained from across the network. A cloud manager can cause one or more network switches or other routing or communication processing components to deny communication access between user-accessible ports on a machine or device and the provisioning systems, or other specific network resources, such that the user cannot cause the host machine to pull information from those resources upon a restart or reboot of the machine. Further, various actions can be taken upon a reboot or attempted reboot, such as to isolate the host machine or even power off the specific machine.

Abstract: A system for performing computing operations in a data center includes one or more sets of computer systems, one or more primary power systems, and a reserve power system. The primary power systems include at least one power distribution unit that supplies power to at least one of the sets of computer systems. The reserve power system automatically supplies power to at least one of the sets of computer systems if a condition is met (such as a failure of the primary power system).

Abstract: A system that implements a scalable data storage service may maintain tables in a non-relational data store on behalf of clients. The system may provide a Web services interface through which service requests are received, and an API usable to request that a table be created, deleted, or described; that an item be stored, retrieved, deleted, or its attributes modified; or that a table be queried (or scanned) with filtered items and/or their attributes returned. An asynchronous workflow may be invoked to create or delete a table. Items stored in tables may be partitioned and indexed using a simple or composite primary key. The system may not impose pre-defined limits on table size, and may employ a flexible schema. The service may provide a best-effort or committed throughput model. The system may automatically scale and/or re-partition tables in response to detecting workload changes, node failures, or other conditions or anomalies.

Abstract: The state of firmware for devices on a provisioned host machine can be validated independent of the host CPU(s) or other components exposed to the user. A port that is not fully exposed or accessible to the user can be used to perform a validation process on firmware without accessing a CPU of the host device. The firmware can be scanned and a hashing or similar algorithm can be used to determine validation information, such as hash values, for the firmware, which can be compared to validation information stored in a secure location. If the current and stored validation information do not match, one or more remedial actions can be taken to address the firmware being in an unknown or unintended state.

Abstract: A system for generating electrical power includes one or more turbine systems, a linking system, a power receiving station, and a transmission line. The turbine systems includes a turbine, a turbine carrier that can hold the turbine in a flow of water, and a generator that produces electricity from rotation of a runner of the turbine. The linking system couples the turbine carriers to a fixed location. The transmission line transmits power from the generator to the power receiving station.
